Renewable Fuel Standard Program

Fuel Pathways under Renewable Fuel Standard

In 2010, EPA established a process for companies to petition for new fuels pathways to qualify for Renewable Fuel Standard (RFS). A fuel pathway is a specific combination of three components: (1) feedstock, (2) production process and (3) fuel type. Assessment of lifecycle greenhouse gas (GHG) emissions is necessary to determine which fuel pathways can qualify. Follow the links below to learn more about fuel pathways and whether you should submit a petition for a new fuel pathway.
